Kinda hack, but if you choose a different currency, the tiers are lower. (With Revolut you can use almost any currency and FX fees are 0-0.5%).

For example with PLN min tier is 12 PLN = 2.64€

This month I donated in Indian Rupees (just like I do with YouTube Premium family), every month I will pick a different currency (tbd). With YT I had to figure out an existing address in India, with Signal it seems I can pick any (even tho my number starts with +31).

In Euros it tells me 2,62 € is the minimum.
